Stupidity is a lack of intelligence, understanding, reason, or wit. It may be innate, assumed or reactive. The word stupid comes from the Latin word stupere. Stupid characters are often used for comedy in fictional stories. Walter B. Pitkin called stupidity "evil", but in a more Romantic spirit William Blake and Carl Jung believed stupidity can be the mother of wisdom.
